Waterless gravity bong for use with cannabidiol (cbd) products

ABSTRACT

A waterless gravity bong includes a housing forming an interior air chamber. A removable cap is positioned at one end of the housing while a bowl is positioned to extend into the removable cap for holding combustible herbal products. A plunger is configured to move within the air chamber for pushing and pulling air within the chamber. The plunger draws ignited smoke from the bowl into the air chamber such that the bowl can be removed for allowing the ignited smoke to be forced from the air chamber into the user&#39;s lungs during an inhaled breath.

FIELD OF THE INVENTION

The present invention relates generally to devices for smoking tobacco and herbal substances and more particularly to a waterless gravity bong.

BACKGROUND

A bong is a filtration device generally used for smoking tobacco, cannabidiol (CBD) products such as cannabis and/or other herbal substances. As seen in prior art FIG. 1, a bong 100 includes body 101 where a bowl 103 connects with a stem 105 that is attached to a side of the body 101. The bowl is filled with a combustible herbal product 107. An interior 109 of the body 101 is partially filled with water 111. The herbal product 107 is ignited and the smoke 113 is drawn though suction through the water 111 via a plurality of bubbles 115. The water 111 acts as a filter to refine and buffer the smoke 113 so that it has fewer impurities and is cooler in temperature. When smoking a bong, the smoker must inhale producing a vacuum inside the bong the bubbles 115 containing smoke begin to come from a stem 105 holding the bowl 103. Once the bong 100 has an adequate amount of smoke 113 built up, either an inlet vent is uncovered or the stem is separated from the bong, allowing the remaining smoke 113 inside the bong to be inhaled though the mouthpiece 117.

Thus, the usage of a typical gravity-type bong requires water 111 to be filled into the body 101. This process is inconvenient and requires that filtered water, which often is dark and has an odor, to be properly disposed. Also, the water often removes much of the tetrahydrocannabinol (THC) from the smoke which reduces the effects of the smoking experience Hence, new solutions are needed for smoking CBD and other products to maximize the user experience.

DETAILED DESCRIPTION

Before describing in detail embodiments that are in accordance with the present invention, it should be observed that the embodiments reside primarily in combinations of method steps and apparatus components related to a waterless gravity bond for use with tobacco, cannabidiol (CBD) and other herbal smoking products. Accordingly, the apparatus components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.

In this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

FIG. 2A is perspective view of a waterless gravity bong in its inserted position ready to draw smoke into the chamber. FIG. 2B illustrates the bong where the position of the plunger is extended for drawing smoke from the bowl. As seen in both FIG. 2A and FIG. 2B, the waterless gravity bong 200 includes a long and narrow tube or housing 201 having a removable cap or top 203. The housing 201 typically has a smooth inner and outer surface and can be made of plastic materials or the like. No water or other fluid is contained within the housing 201. In alternative embodiments, the cap or top 203 can be a grommet like device or may be hinged to swing from the top of housing 201.

A piston or plunger 205 is configured within the housing 201 where one end of the the housing is sealed using a top 203. The top 203 is configured to be held in a fixed position at a top end of the tube or housing 201. As further described herein, a bowl 207 is positioned within opening 206, allowing combusted contents of the bowl to enter and exit the housing 201. The combused contents are the resulting of igniting the contents of the bowl. The plunger 205 forms a seal with the interior of the housing 201 even when it is moved through the housing allowing the interior volume of the housing 201 to be increased or decreased.

FIG. 2A illustrates the plunger rod 209 pushed near the top of the housing 201 enabling the smoker to easily ignite tobacco or herbal substances in the bowl 207. As the herbal substance is ignited within the bowl, the smoker pulls the plunger rod 209 using handle 213 downwardly which acts to pull or draw the smoke of the burning herbal smoke into the air chamber 211. The handle may have a ball or looped end to facilitate pulling or pushing with a finger.

As seen in FIG. 2B, once the chamber 211 is full of smoke, the smoker can remove the bowl and move the plunger 205 upwardly so the compressed gas, composed of smoke and/or air within the chamber, through opening 206 into the user's mouth and lungs. This provides the smoker the ability to smoke an entire bowl of product in one inhale or “hit” without the need to continually relight the bowl. After the bowl 207 is removed, the invention provides a relatively easy way to inhale a substantially large amount of combusted herb by forcing compressed smoke back into their lungs after the bowl is removed from the top. The cap only need be removed for cleaning. Since no water is used, embodiments of the device operate as a waterless gravity bong allowing containment of combusted tobacco or herbal products. In other embodiments, one or more LEDs or lighting devices 215 might also be used within the housing 201 to aid in viewing combusted materials in low light conditions. The light is positioned at the top of the plunger 205 and moves linearly with the plunger 205 though the housing 201 emitting light and illuminating the contents of the housing 201.

Thus, embodiments of the present invention are directed to a waterless gravity bong having a housing forming an interior air chamber where a removable cap is positioned at one end of the housing. A container or bowl is positioned to extend into the removable cap for holding tobacco or a combustible herbal product. A plunger is configured to move within the air chamber for pushing and pulling air within the chamber. In use, the plunger draws ignited smoke from the bowl into the air chamber such that the bowl can be removed for allowing the ignited smoke to be forced from the air chamber into the user's lungs during an inhaled breath.

In the foregoing specification, specific embodiments of the present invention have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the present invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present invention. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims.
